PAPER-PUNCH.

SPECIFICATION forming part of Letters Patent No. 450,224, dated April14, 1891.

Application filed June 1'7 1890. Serial No. 355,709. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT B. DICK, a citizen of the United States,residing at Chicago,

' in the county of Cook and State of Illinois,

have invented anew and usefullmprovement in Paper-Punches, of which thefollowing is a specification.

The object of the invention is an eifective paper-punch of economicalconstruction.

In the accompanying drawings, forming part of this specification, Figure1 is a plan view of the blank which forms the body of the punch, showingthe same after it has been stamped and before bending. Fig. 2 is a sideelevation of the same after bending with the punches in place, and Fig.3 is a front elevation of the same.

The blank or of the punch is formed from spring metal by stamping from afiat plate at a single operation and subsequently bending.

I) b are holes which receive the screws or other attaching devices whichsecure the punch, when desired, to a suitable base.

0 c are holes of larger diameter than the holes b b, stamped out in suchposition that when the plate a is bent, as shown in Fig. 2, the holes 0will be directly above the holes I) and will permit a screw-driver to beoperated to force the screws home in the holes b 1), whereby the punchis secured to its base.

d d are holes through which the male punches e 6, carried by bar f,project.

9 is ahole through which a screw is adapted to pass to secure both thehandle hand punchcarrying bar f in place. The right-angular cut 11 i ateach side of the plate a is made for the purpose of permitting thepartially-severed portion j to be bent, as shown in Figs. 2 and 3, toform both the paper-guide and female member of the punch.

k k are holes cutout of the severed portion j, and Z Zare holes cutoutof the blank a, which, when the portion j isbent, as shown in'Fig. 2,are directly opposite the holes, and form, together with the holes is,the female member of the punch. The bending of the blank a to form theupper plate of the punch takes place ing taking place about on thedotted line 00 0c of Fig. 1 and being a very gradual one as shown inFig. 2. By locating the bend rear- Wardly of the attaching-point thedurability of the punch is increased, as there seems to be no tendencyof the spring metal to crack on the line of its bending.

The male members ofthe punch care formed with a V-shaped cut, so that anadvanced cutting portion will be presented on the downward motion of thepunch, the action of which will be to effect a gradual cutting of thepaper on two sides rather than a positive stamping out of the paper or acutting on one side only.

It will be seen that a punch constructed as above described iseconomical of manufacture and efficient in operation.

What I claim is- In a paper-punch, the combination of a spring-metalblank comprising an upper and lower plate in one piece, male-punchmembers carried by the upper plate, and a paperguide for each punchmember, comprising a partially-severed bent strip on the lower plate,said bent strips being provided with holes to permit of the passage ofthe male punches, substantially as set forth.

This specification signed and witnessedthis 14th day of June, 1890. 0
